SHOGKING MACI-IINE.

Application filed March 30, 1918.

To all whom it may concern:

Be it known that I, CHRISTIAN NYGAARD, of the city of Moose Jaw, in the Province of Saskatchewan, Canada, have invented certain new and useful Improvements in Shocking-Machines, of which the following is the specification.

The invent-ion relate to improvements in shocking machines and the principal object of the invention is to provide a machine to accompany the ordinary binding machine and which will receive the sheaves ejected from the deck of the binder, collect and form the sheaves into a shock and deposit the shock butt down and establish it firmly on the ground and will then reset itself to remachine with which it is associated, these ceive further sheaves.

A further object of the invention is to provide a machine which will compress the heads of the sheaves prior to depositing the stock whereby a good base is given the stook and the same will on such account he more firmly planted on the ground.

A still further obect of the invention is to construct a machine wherein the sheaf receiving and shock forming basket is free to pass back to accommodate the deposited stook, thereby preventing, to a great extent, the upsetting of the stock due to the forward travel of the machine. 7

With the above general and other minor objects in view, which will become more apparent as the description proceeds, the invention consists essentially in the arrangement and construction of parts hereinafter more particularly described and later pointed out in the appendedclaims, reference being had to the accompanying drawings in which Figure 1 represents a side view of the complete shocking machine in the normal or sheaf receiving position.

Fig. 2 represents a plan view of the same with certain parts of the binding machine shown.

Fig. 3 represents a front view of the machine and part of the binding machine.

Fig. 4 represents a view similar to Fig. 1 but with the machine shown in the position it takes just shortly after the shock has been deposited.

Fig. 5 represents a side view of part of the machine showing one of the basket hangers and adioining' Specification of Letters Patent.

Serial No. 225,804.

Fig. 6 represents an enlarged detailed side view of the clutch and associated parts with the clutch in engaged position.

Fig. 7 represents a view similar to Fig. 6 with the clutch in disengaged position.

Fig. 8 represents an enlarged detailed l'ongitudinal sectional view through the pressure crank.

Fig. 9 represents a side view of the starting trip.

In the drawings like characters of reference indicate corresponding parts in the several figures.

In order that the shocking machine may be better understood I have considered it advisable to show the parts of the binding being the binder frame 1 and deck 2, the shocker being attached to' the binder frame in a location such that the conveyer thereof receives the sheaves delivered or ejected from the deck. The shocking machine is now described in detail.

3 represents an open ended substantially rectangular main or under frame fitted with a rearwardly extending supporting caster wheel 4 and provided forwardly with suitable bearings 5 and 6 which receive pivotally a cross shaft 7 on the outer end of which I mount a driving wheel 8 and a driving chain wheel 9 adapted to rotate with the wheel 8. The inner side of the machine frame is fitted with extending arms 10 and 11 which are pivotally secured at 13 to the binder frame. Four corner posts 14, 15, 16 and 17 extend upwardly from the main frame and support a top frame like structure comprising cross beams 18 and 19 and lengthwise extending beams 20 and 21.

From the above it will be apparent that the lower andv upper frames together with the corner posts form an open box like framework which framework is utilized to support and contain the sheaf receiving and shock forming basket 22.

This basket is of the ordinary form, being somewhat cylindrical in shape although con-' tracted at the rear end and provided with an open top 23 through which the sheaves are deposited to fill the basket. The basket is suspended by a yoke shaped supporting shaft 24 which is permanently secured tot-he basket and has the ends thereof extending short horizontslij stub shafts and 26 which terminate in ball ends 27, the balls being received within sockets 2S and 29 presented by vertically disposed sleeves 30 and 81 slidably mounted on vertically disposed guide shafts or hangers 32 and 33 located at opposite sides of the framework and having their upper ends pivotally secured by pivot pins 34 to the memhere 20 and 21 of the top frame. The lower ends of these guide shafts terminate short of the under frame so that they swing clear of, the same.

At the front of the shocking machine I locate a counter shaft 35 carried in suitable bearings 36 and 37 fastened to the corner posts 14 and 1 7. The counter shaft is fitted with a pair ofspacedpulleys 38 and 39'fixed to the shaft and provided with extending winding cables, straps, cords or such-like 40 and 41 which pass from the pulleys upwardly over guide pulleys 42 and 43 secured to the top frame and then project downwardly and are permanently fastened to the sleeves.

From the above arrangement it will be obvious that when the counter shaft is turned-in a clockwise direction the straps will wind on the pulleys and draw up the sleeves thereby raising the basket; The basket is retained in the horizontal sheaf receivingiposition by the action of a weight 44 secured to the rear end'of it and causing it to tilt backwardly and the action of a stationary cross bar 45 secured to vertically disposed carrierbars 46 and 46 spaced from the guide shaftsbut having the ends brought in and permanently fastened tothe guide shafts.

To explain-the above action itwill be seen by referring'to Fig. 1 that the basket in the normal position is held up by the straps and is-held in the horizontal position by the action: of the weight tilting the rear end down against: the bar 45. The counter shaft is intermittently driven by the chain wheel 9 in the following way 47is a-chain wheel mounted rotatably on i the outer end of the counter shaft and connected by means of a chain 47 to the chain wheel 9. The chain wheel 47 is formed with a: clutch member 48 which rotates with it and directly opposing the latter clutch mom ber is afurther clutch member 49 formed at the end of a sleeve 50 feathered as indicated at '51 on the counter shaft. The sleeve is prowhich face spirals for approximately threequarters of a revolution in a direction toward the gear wheel. The cam is also fitted with a disengaging trip 57 adapted in the rotation of the sleeve to catch the pin and throw it back to disengage the clutch members.

A more full description of this action will later be given.

In the normal or up position of the basket it will be seen that it has a natural tendency to fall, swinging over on the-bar, the sleeves sliding down. This natural tendency is overcome by providing the inner end of the counter shaft with an: extending striker 58' which, in the up or normal-position of the basket, is engaged bya bell crank 59 pivotally secured to the corner post 17'. The bell" crank normally engages the striker and to the bell crank I connect'a link 60, the lower end of which is secured to a crank- 61 located at the outer end of an operating shaft 62 passing to thebinder and fittedwith any suitable appliance. whereby the: attendant of the binder can, when desired, rotate the shaft.

From this it will be obvious that the basket is normally locked in the up position sure crank 65 which, in the. rotation .of'thecounter shaft, is adapted to engage with the lower end of the pressure plate andforce the same inwardly toward the basket, this action being utilized to compress the sheaveswithin-the basket as the basketv passes to dumping position.

The pressure crank comprises a sleeve 66 fitted with aspring pressedplunger 67, the outer end of which carries a roller 68.

In order to deliver the sheaves to the basket, which has a more or less elevated position in respect to the deck, I provide anelevator 69 which has the lower end supported from the bars 10 andll and the up er end supported fro-m the top frame of the shocker.

This elevator is provided with two endless conveyers 70 and 71 suitably driven from the.

binder mechanism and arranged such that the sheaves delivered or ejected from the deck are passed upwardly between the conveyers and ejected from the conveyers over a chute 72 into the basket.

I have not entered into the details of the construction of the elevator as it is of ordinary construction and is only shown asa. means for elevat1ng. theisheaves. from. the

deck to a position where they can be delivered through the open top of the basket into the same- I When this machine is in use and the basket is in the normal position the sheaves passed from the deck are delivered by the elevator to the basket. As soon as the attendant considers that enough sheaves are in the basket to make a proper shock he actuates the shaft 62 to release the striker. Immediately this occurs the basket drops by gravity until it takes initially a position as shown in dotted outline in Fig. 1. In dro ping it rocks over, so to speak,on the bar 45 which remains stationary at this time. As the basket drops the straps unwind and rotate through the pulleys 38 and 39 the counter shaft, in the present instance, approximately three-quarters of a revolution. As the counter shaft rotates the pressure crank turns over to bring the roller 68 into engagement with the pressure plate and force the pressure plate inwardly to effect the compression of the heads of the sheaves within the basket and the consequent spreading of the butt of the stook.

In rotating the three-quarters of a revolution as above stated the counter shaft causes the sleeve 50 to rotate three-quarters of a revolution and makes the pin 53 climb the face 56 with the result that when the basket has dropped the full distance the face 56 of the cam has moved the pin so that the clutch members are brought into engagement. During this action the spring 54 is compressed. Immediately the clutch members engage the shaft is driven in the opposite direction by the chain wheel 47 which is rotated at all times by the wheel 9 and the pin 53 then commences to turn back from the position best shown in Fig. 6 toa position where it is hit by the extending trip 57 which draws the pin in to disengage the clutches, and immediately this occurs the spring operates to force the bell crank back to the initial position as shown in Fig. 7. During the interval that the clutch members are engaged the straps are rewinding on the pulleys and the basket is raised and, 0wing to the action of the weight 44, takes its initial receiving position.

In considering the action of the basket at the time the sheaf is deposited it will be obvious that the basket is free to swing axially at the ball and socket joints to clear the stook and is also free to swing bodily backwardly owing to the fact that the upper ends of the hangers are piwoted to the top frame. This back swinging feature allows the basket to steady the depositedstook for a short interval as it will be borne in mind that the instant the stook touches the ground the machine is moving in respect to it and the back swing allowed the basket accommodates the forward. movement of the ma chine to allow the basket to stay with the stook a short interval.

After the basket has returned to its normal position the clutch automatically disengages in the manner hereto-fore disclosed and the basket remains in the up position until the attendant again wishes to dump the stook. The action is then repeated for successive stooks.

In the above description it will be readily understood that various details could be readily modified without departing in the slightest from the spirit of the invention as covered by the appended claims.

What I claim as my invention is 1. A shocking machine comprising in combination a framework, a pair of vertically disposed side hangers having their upper ends pivotally secured to the framework, a sheaf receiving and shock forming pivoted basket contained within the framework and slidably mounted on the hangers, releasable means holding the basket in the sheaf receiving position at the upper end of the hangers, means for up-ending the basket when released to slide downwardly on the hangers and means for returning the basket to normal positionafter dumping the stook.
